Race nutrition depends not only on the length of the race, but any number of variables like terrain, weather, and your personal preferences.

There are, however, a few strategies and rules I like to follow when planning out my race day nutrition. In today’s episode of Trail Talk, I share my basic approach for fueling a marathon on up to a 100-mile ultramarathon.

Author Doug Hay is the founder of Rock Creek Runner, host of the Trail Talk podcast, and fanatical about everything trail running -- beards, plaid shirts, bruised toenails, and all. He and his wife live and run in beautiful Black Mountain, NC.

One thought on “What I Eat During a Marathon, 50K, 50-Mile, 100K, and 100-Mile Ultramarathon”

I ran a road marathon a few years ago that advertised gels at several aid stations, so I didn’t bother carrying any of my own. I regretted that when some of the gel stations that were advertised ended up not being on the course and I didn’t find a gel until the midpoint of the race, which was about an hour later than I wanted to start taking them. Ever since that experience, I’ve always carried most or all of the gels I think I’m going to want during a race so that I don’t end up getting harmed if the race organizers don’t deliver.
